A sensitivity analysis of the flood safety of Solaimantangeh dam using a regional climate change simulation is presented. Based on the output of the CCSM (Community Climate Change System Model) general circulation model, the NIRCM (North of Iran Regional Climate Model) computes regional scale output with 50 km spatial resolution and 21 vertical layers. Using the SRES (Special Report Emission Scenario) “B1” Climate Change Scenario when applied to the Tajan river basin, where Solaimantangeh dam is located, NIRCM reduces significantly the bias in Annual Maximum Event total Precipitation (AMEP) & Annual Maximum Daily Precipitation (AMDP) that CCSM shows. The stream flow change scenario is then simulated using SSARR (Stream flow Synthesis and Reservoir Regulation) model. A rainfall-runoff model was implemented using precipitation and temperature projected by CCSM and NIRCM. The model demonstrated that average Stream flow would increases 38.7% and the variability would increases 14.3%. This remarkable increase in projected annual maximum flow for the next 20 years (2004-2023) should be a significant negative signal to water resources managers. The results indicate that the number of floods remains almost the same, but that the magnitude of a single flood event and the recovery from it become worse.

Plants as the life giving entities have important role in mental and physical health of human. In the modern time with expansion of the cities and increase of industrial centers and living style change and decrease of social negligence about green spaces as the factor for mental diseases, altogether have been propounded for many psychologists and physicians. In this way considering green spaces is necessary to peace of mind. This article intends to study sense and visual capabilities of artificial green spaces using descriptive method and their effects on human. The results show that connection with green space directly or using senses can contribute to reach mental health. It is hoped this research can provide conditions to further researches.

The aim of this study was to investigate the role of coach-oriented organization and team performance in the mental health staff General Directorate of Youth and Sport of Ardabil. Descriptive and correlational methodology has been applied to the target and the field was done in this study population all staff General Directorate of Youth and Sport was Ardabil province in the number of them 85 persons. Limited due to the small population size of the population sampled and analyzed, so is the population size and sample size. To collect data from questionnaires in coach-oriented organization and team performance staff (researchers) and mental health (Goldenberg and Hiller, 1979) was used. To analyze the data descriptive statistics (frequency tables mean and standard deviation) and inferential statistics (Pearson correlation and multiple regressions) is used in which the coach-oriented organizational relationship with the staff in mental health and team performance The SPSS19software were analyzed. The results showed that between team performance and organizational staff coach-oriented relationship (r = 0.314), there was a significant (p <0.05). Inter coach-oriented physical and mental health relationship (r = 0.352), there was a significant (p <0.05). Inter coach-oriented and anxiety, social dysfunction and depression there is a significant negative correlation (p <0.05). The mental health of a coefficient of 88% could predict the coach-oriented organization.

Nowadays, Spatial and social inequalities are universal and expanding phenomenon. Identification and spatial analysis of social, economic and ecological inequalities in metropolises is one of the essential and basic proceeding for planning and achieving urban sustainable development. The present research method is descriptive-analytical and using 13 sub criteria based on three main criteria of social, economic and environmental analyzes the status of spatial fragmentation among the metropolis Tehran's districts. For this purpose, the criteria and sub- criteria's internal and external dependencies was determined using the Delphi and ANP method in Super Decisions Software and assessed and scored relative to each other. The results of assessing the indicators shows that Tehran metropolis lacks of the physical unity and spatial heterogeneity between the north and south of the city remains as main feature of its spatial structure. It is necessary that the authorities of Tehran urban management to take actions for better understanding of this phenomenon and consequently offer new and efficient solutions for reducing the effects of various impacts of spatial inequality and duality. For this reason, it is essential to rethink the concept of city in terms of social, economic, political, and ecological and sustainability dimensions.

Today, Information Technology services are considered as valuable resources in all areas. For making Information Technology Management Processes purposeful and efficient in different organizations &ndash as a competitive and strategic advantage (especially in organizations responsible for health care services) &ndash it is necessary to recognize the level of maturity of the organization and review its processes in the field of Information Technology Services. On the other hand, finding the relations between main components of maturity and Information Technology Standards are essential to make them functional. In this paper, in addition to recognizing the present IT Management Services and prioritize them we reviewed the gap between processes and compare them to provide related maturity levels for introducing a localized model in Information Technology Services maturity in organizations responsible for health care services. Therefore, with the help of health experts and professionals working in health organizations we categorized indicators in 10 management processes and 9 criteria related to it. In addition, we evaluated overlapping levels of maturity and ITIL management processes by using experts opinions that have a high percentage of consensus in the field of selecting criteria. The aim of deriving these indicators was creating a functional tool in health organizations and paying attention to its main differences with other methods in addition to inspiring from CMMI and entering effective components on Information Technology Infrastructures Standard (ITIL) framework according to functional views in Information Technology Management Services at the Tehran University of Medical Sciences. The present study can be recognized an applied research in accordance with its goal. In this research, a proposed instrument is used for gathering data (ITILRA questionnaire) from health care centers of Tehran University of Medical Sciences. The aim was determining the gap between current organizations management processes with an optimal one in the field of IT services (which are at different levels of maturity) with respect to the ITIL.V3 framework. For this reason, leveling joint processes between ITIL and CMMI and approving corresponding indicators at Information Technology Services Maturity Model levels were done and each criteria and processes were compared with ideal and standard situation separately. Then, we determined the highest and lowest differences rates and standard deviation for creating a localized maturity model based on ITIL. In management process, Service Desk has the most close and overlapped situation with ideal condition. In Configuration Management, the highest differences and gap was recognized, so, it should be closer to optimal condition. Service Desk belongs to Service Operations phase and it indicates the maturity level of the organization. As it was expected, it was in a very desirable condition. Configuration Management Process belongs to Translating Service Phase which stood in third place (predetermined processes) of maturity level in CMMI Model. It shows that improving maturity level of the organizations needs more efforts for reducing or omitting any gap between the current situation of the organization and a desirable condition. All these scores (by mean and standard deviation tests) obtained using SPSS software.

In today's communities achieving to effectiveness of urban advertising is one of troubles of advertisement industry.

Quality of urban areas and improvement of it have always been considered as one of the main issues in the process of urbanization. It might be possible to consider this importance as the result of fundamental changes in intellectual patterns during the past two decades in one side and its proposal in all aspects of human life on the other side though this is one of the main influential concepts in urban landscape and vision, and there are various approaches available regarding this matter. These approaches have decreased the nature of landscape concept to simple decorating concept and even considering it equal to any type of interaction between human and environment and it identification. So there are several results for each definition in terms of planning and management. Urban landscape &ndash as the objective of city &ndash is the most impressive urban index for human beings. The issue of lack of attention to city vision and landscape, and efforts in identifying and creating of it, is one of the most important problems of cities. Increase in Population as a threat to city life, migration of rural population to urban areas and large cities, traffic, air pollution, open space, green space and playgrounds and several other issues, are among the items that have been discussed relatively more than issue of urban landscape and its problems and more papers and books have been written on it. Urban landscape is in fact all the elements that can be seen in the city and can be watched by human eyes. These items form urban landscape when they are integrated and combined with several factors in every moment. This article seeks to enhance the environmental quality to organize urban landscape in Sa&rsquodi Street through discovery of historical meanings, cultural codes and local architectural terms in visual landscape of the city, and giving sense to it in physical and visual formats. Therefor with review of Store street in New York &ndash as an foreign sample - and Hamze street in Isfahan &ndash as a domestic sample &ndash the existing situation of Sa&rsquodi street is reviewed and SWOT analysis is then implemented for examining the weaknesses and strength factors and regulating the urban landscape of this street through field-documentary studies.
